Strike TRIBUS Enhanced Castle Nut and End Plate AR-Style Buffer Tube Red

The Strike TRIBUS Enhanced Castle Nut & Extended End Plate system is an upgraded receiver extension (buffer tube) hardware set designed to improve sling mounting versatility and weapon handling. Building on Strike’s earlier enhanced castle nut/end plate design, TRIBUS adds additional Quick Detach sling mounting points to the extended end plate for greater left/right/center sling placement flexibility. The extended QD sockets are positioned to reduce interference with the shooter’s primary hand, helping prevent pinching during manipulations in tight spaces or under stress. The castle nut also features an anti-rotation/anti-walk set screw designed to help prevent the nut from backing out during use while still allowing serviceable disassembly. Finished in an anodized red color, TRIBUS delivers both functional and aesthetic upgrades for AR-pattern builds.
